Application led December 24, w26. Serial No. 155,953'.

My invention has for its object to provide a simple and highly eilicientsanitary well casing cap and drop-pipe clamp, and to this end itconsists of the novel devices and combinations of devices hereinafterdescribed and defined in the claim.

As is well known, driven or drilled wells are dug the first few feet toform a pit that is covered with a pump platform and the top of the wellcasing is usually open and termi-V pipe. The cap also forms avconnection he# tween the drop-pipe and casing and prevents saiddrop-pipe from lifting under the pump ing action of a windmill.

In the accompanying drawings, which illustrate this invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view of a well pump having this invention applied to thecasing and droppipe; and

Fig. 2 is va view partly in elevation and partly in central verticalsection showing the invention and portions of the casing and drop-pipeto which it is applied.

The numeral 3 indicates a well pit. covered by a pump platform l, andthenumeral 5 indicates a well casing, the top of which terminates insaid pit, just above the bottom thereof.

Mounted on the platform l is a pump 6 having an air chamber pipe 7extending into this pit and connected to a branch coupling 8 interposedin a drop-pipe 9, above the top of the casing 5. Said drop-pipe 9extends axially into the casing 5. Leading from the branch coupling 8 isa discharge pipe 1() which extends above the platform l and has 'at itsupper end a spout 11.

The parts thus far described are of standard and well knownconstruction.

Referring now in detail to the improved cap which is indicated by thenumeral 12., the same is provided with an axial passage 13 through whichthe drop-pipe 9 extends. The

flange of the cap- 12 is internally stepped by progressively decreasingthe diamcterithereof upward to form a. plurality vof axially spacedcylindrical sections 14, the tops of which afford shoulders 15. rlhesecylindrical sections lelare of such diameters as to telescopicallyrecover casings of different sizes. lt will be noted that the 'casing 5fits into the 'cylindrical sections of the smallest diameters,

and a gasket 16 is interposed between the re? spcctive shoulder, whichin the present instances is the under surface of the top of the pap 1Q,and the upper end of the casing 5. W hen the cap 19. is applied to acasing lai-ger than the casing 5 a gasket will bc provided to fit therespective shoulder 15. Obviously, this gasket 16 forms a water-tightjoint between the cap 12 and casing 5. Y

Enibodied in the cap 12,'at its passage 13, stuffing box 1.7 containinga packing 18 that is compres. ed onto the drop-pipe 9 bythe gland ofsaid stuffing box. rlhis packing 18 not only forms water-tight jointbetween the cap 12 and drop-pipe 5, but it frictionally clamps said capto the drop-pipe and prevents lifting thereof under pumping action'. Y

This cap'12 is rigidly and det-acliab-ly secured tothe casing 5 by aplurality of circumferentially spaced set screws 19 that have threadedengagement with the flanges of the cap 12. at its internal sections 14`of the greatest diameter, and arranged to impinge against the casing 5.By locating the set scr ws 19 as shown, the same may be used forsecuring the cap 12 to all of the different sized casings 5 to whichsaid cap may be applied.

casing and the exclusion of animals, rep? tiles, insects, and othervermin and thus keeps the water in the well in a sanitary condition.

. What l claim is:

A well casing cap and drop pipe clamp havinga drop pipe passage.y theflange of the cap being arranged to be loosely telescoped ico onto aWell casing, an annular internal packing in the cap, means forcompressing the packing to contract the same onto adrop pipe extendingthrough said passage for frictionally holding said pipe aga-inst liftingmovement during pumping action, a compressible gasket in the caparraliged to rest on the upper end of the easing and support the capthereon and be compressed therein)r to seal the joint between said capand caslng, 10`

and a Set screw having threaded engagement with the fiangeof the cap andarranged to mpinge against the casing. In testimony whereof I aixmysignature.
